UNSPSC 51283951: Sulfamethoxazole sodium

This classification denotes a sulfonamide anti-infective agent C10H10N3O3S.Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier PJ0X8H59AI, chemically known as benzenesulfonamide, 4-amino-n-(5-methyl-3-isoxazolyl)-, sodium salt (1:1), but more generally known as sulfamethoxazole sodium, which bears US NIH Compound Identifier 5329. European Medicines Agency schedules Sulfamethoxazole sodium in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB35068.

Most nations, for tariff and trade purposes, schedule sulfamethoxazole sodium under HS 29350090 and SITC 51580. As of Q4 2014, SULFAMETHOXAZOLE SODIUM remains US FDA's Preferred Term for this commodity. SMILES: CC1CC(NO1)[N-]S(=O)(=O)C2CCC(CC2)N.[NA+].

UNSPSC 51283951 Sulfamethoxazole sodium is a Commodity code covering antibiotic pharmaceuticals for state and local government health and emergency response programs. However, the recent opportunities tagged under this code show substantial misalignment with sulfamethoxazole sodium specifically — none of the posted solicitations actually request this antibiotic. Instead, state and local buyers are soliciting broader pharmaceutical categories: naloxone and drug deactivation systems (emergency overdose response), generic multi-source pharmaceuticals and OTC products through cooperative purchasing, direct-to-manufacturer pharmacy programs, and medical and first aid supplies for emergency responders. The code as applied appears to serve as a catch-all for pharmaceutical procurement across health departments, emergency services, and state HHS agencies, though the sourcing activity does not target this specific drug formulation in the recent record.

Issuing bodies include county health departments (Seminole County, Florida), state health and human services commissions (Texas HHS), municipal fire departments (City of Tampa), and multi-state cooperative purchasing alliances (Minnesota Multistate Cooperative Purchasing Alliance, serving Minnesota and Oregon). Recent opportunities span Florida, Texas, and the Upper Midwest through cooperative arrangements. The Minnesota MMCAP RFP for generic multi-source pharmaceuticals and OTC products (due March 26, 2026) and the Texas HHS Commission RFI on direct-to-manufacturer prescriptions (April 3, 2026) represent the largest-scope recent activity, targeting multiple jurisdictions through cooperative or state-level contracting. The City of Tampa's IFB for medical and first aid supplies to the Tampa Fire Department Rescue Division (due March 13, 2026, estimated contract value $700,000) includes an SLBE set-aside with a 5 percent bid discount. Seminole County's IFB for naloxone and drug deactivation systems (due July 26, 2023) solicits 1,900 units of naloxone and 800 deactivation systems annually with quarterly deliveries. The mismatch between the sulfamethoxazole sodium commodity code and the actual pharmaceutical procurement activity warrants clarification with state and local procurement offices on appropriate code assignment before pursuing opportunities under this classification.
